I know just a tiny bit about this even tho' there are acres of mustard hereabouts. You can do a search of the Univ. of Idaho website and see what they are up to in developing commercial varieties.

The mustard for condiments are not all the same. Yellow mustard seed is, apparently what is used for "hot dog mustard." And, the Oriental mustards are also commercially grown in Idaho and other places for condiments. So, you have choices Stoneunhenged - brown, yellow, Oriental, and I believe there are others.

I grow Asian broadleaf mustard every year as a green in the garden. Tempted to say that a lot of different mustard seed is appropriate for condiments but I'm a little unsure. It wouldn't cost much to buy a pound of seed, grind some of it, and see how you like it - - if you were to make your purchase from the seed sold for sprouts:

Johnny's sells brown mustard for sprouts, $6.55/pound. Sproutpeople sell Oriental yellow mustard for sprouts, $7.85/pound. Mumm's has Oriental mustard for sprouts, $10.25/kilogram.

And BTW, mustard is a super choice as a cover crop.

Stores which sell Indian foods have inexpensive mustard seed in bags of 1/2 or 1 pound or so. I don't know if it is suitable for the type of condiment you want. It would be an inexpensive source of seed for a cover crop.

I won't disagree with Steve about yellow mustard seed for making yellow mustard, but that bright yellow French's mustard also has turmeric in it, which is yellow.

Initially I would have guessed that all spices are irradiated to kill pathogens and that process would render the seed unviable. However that is not the case. I used whole mustard seed From a major spice company as a cole crop seed diluter and I had mastard seed growing everywhere.

There are a host of spice companies that would sell you mustard seed at a very reasonable price. It often is much cheaper than the bologna meat that it is added to, thus the USDA limit of 3% in such products.

Thanks for all the good info. I ordered some seeds from heirloomseeds.com.
